The Asiatic lions, squirrel monkeys and penguins were among the animal inhabitants at London Zoo to get a feast of seasonal treats on Thursday all designed to allow them to use their natural skills.
The zoo's lionesses Heidi, Indi and Rubi woke up to a pile of gift-wrapped cardboard boxes which they delighted in ripping apart with their claws and the monkeys found festive stockings filled with treats hanging from the climbing ropes in their enclosure.
